Abstract: A display device includes a display panel, a first circuit board, a control unit disposed on the first circuit board, a second circuit board, and a coupling film which electrically couples the control unit and the second circuit board to each other. The coupling film includes a first coupling part including a first region attached to the first circuit board, and a second region overlapping the display panel when viewed in a thickness direction of the display panel, a second coupling part including a third region attached to the second circuit board, and a fourth region overlapping the display panel when viewed in the thickness direction of the display panel, and a third coupling part coupled to each of the second region and the fourth region to electrically couple the first coupling part and the second coupling part to each other.

Abstract: A compressed air producing method, in which two or more adsorption columns, in all or part of which a zeolite-series adsorbent is charged, are switched over to purify feed air and the adsorbent charged in at least one adsorption column of said adsorption columns is regenerated in turn with regeneration gas, is characterized by comprising a step of performing, when an adsorption column (R) in a regeneration step transfers to a purification step, the purge of said adsorbent with purified air, and characterized in that the internal pressure of an adsorption column (R) in the purge step is controlled such that a differential pressure thereof from the internal pressure of an adsorption column (P) in the purification step falls within a specified value.
